Had our first predator attack last night. Assume it was a raccoon or rat. Something burrowed or dug under the duck hose about six inches. Excess dirt in a pile outside. Thinking must have been a raccoon. Whatever it was must have given up rather easily. Thank God. Tunnel was only an inch/inch and a half wide. No visible sign of something turning around and coming out again. :0( Roof lifts up fairly easily - keep telling my husband it's not secure enough to withstand raccoons....
